The Itailian Blood Shower

A singular instance of blood rain, which happened in Messignadi, Calabria, Italy on May 15th, 1890. According to record from the Italian Meteorological Bureau the rain was found to be comprised of migratory bird blood. No corpses or any other body parts from those birds were ever recovered, and there is some debate over what could have caused the rain in the first place. It is the only recorded instance of actual blood raining down.
